Oman made its international debut at the 2009 ACC Women's Twenty20 Championship in Malaysia. The team won only a single match in the group stage, against Kuwait, and were eventually ranked tenth after losing to Bhutan in the ninth-place play-off. At the tournament's 2011 edition, hosted by Kuwait, Oman failed to win a game. In December 2014, Oman hosted the inaugural edition of the Gulf Cooperation Council (GCC) Women's Twenty20 Championship, which was also contested by Kuwait, Qatar, and the United Arab Emirates. The team placed third at the tournament, ahead of Kuwait, and finished in the same position at the following year's tournament, which was held in Qatar.
In April 2018, the ICC granted full Women's Twenty20 International (WT20I) status to all its members. Therefore, all Twenty20 matches played between Oman women and another international side after 1 July 2018 will be a full WT20I. Oman played their first matches with WT20I status in January 2020 during a triangular series against Qatar and Kuwait, which was held in Doha.
